14.7lb/in²
Explanation:
This is a conversion problem from atm to pounds per square inch
Pressure is the combined force per unit area of substance on another.
Given pressure = 0.5atm
To solve this problem ;
Convert from atm to N/m² to pound per square inch
1 atm = 101325N/m²
0.5atm = 0.5 x 101325 = 50,662.5N/m²
now we need to convert to pound per square inch;
1N = 0.225lb
1m = 39.37in
Solving;
101325 N
= 14.7lb/in²
